The One Big Beautiful Bill Act (OBBBA) rewrote the tax playbook for real estate investors. Signed into law on July 4, 2025, it permanently restored 100% bonus depreciation, expanded Section 179, made the 20% QBI deduction permanent, and reshaped incentives like Opportunity Zones and LIHTC.

For anyone running the numbers on a rental, syndication, or commercial acquisition, these six changes shift the numbers in your favor. Here’s what changed and what it means for your next deal.

1. 100% Bonus Depreciation Is Back, and It’s Permanent

This is the headline change. Under the Tax Cuts and Jobs Act, bonus depreciation started phasing down in 2023 and was set to hit 0% by 2027. Investors who bought property in 2025 were staring down a 40% bonus rate.

OBBBA reset that clock. Qualified property placed in service after January 19, 2025 now qualifies for 100% bonus depreciation, with no expiration date written into the law.

For real estate investors, this is where cost segregation earns its keep. A cost segregation study reclassifies components of a building (fixtures, flooring, certain site improvements) into shorter recovery periods of 20 years or less. Those reclassified components now qualify for full, immediate expensing instead of a 39-year straight-line depreciation schedule.

2. Qualified Production Property Gets Its Own 100% Write-Off

OBBBA introduced a new category under Section 168(n): Qualified Production Property (QPP). This allows 100% immediate expensing for certain newly constructed or acquired nonresidential real property used in manufacturing, production, or refining.

This is narrower than bonus depreciation. It applies to the building itself, not just components, but only for qualifying production use. Construction must begin after December 31, 2024 and the property must be placed in service before January 1, 2034.

For investors in industrial and manufacturing real estate, this closes a gap that bonus depreciation never covered. Building shells previously depreciated over 39 years can now, in qualifying cases, be fully expensed in year one.

3. Section 179 Expensing Limits Nearly Doubled

Section 179 lets businesses expense the full cost of qualifying assets rather than depreciate them over time. OBBBA raised the annual limit to $2.5 million, with a $4 million phaseout threshold, for property placed in service after December 31, 2024.

Section 179 works alongside bonus depreciation rather than replacing it. Investors with multiple properties or a mix of qualifying business assets now have more room to front-load deductions, particularly useful for years with unusually high taxable income.

4. The QBI Deduction Is Now Permanent

The Section 199A Qualified Business Income deduction let pass-through entities and landlords deduct up to 20% of net rental income. Before OBBBA, this deduction was scheduled to expire at the end of 2025.

OBBBA made it permanent. For investors holding property through LLCs, partnerships, or as sole proprietors, this removes a planning uncertainty that had been hanging over multi-year hold strategies. Combined with bonus depreciation on the same property, the QBI deduction compounds the after tax return on rental income.

5. Opportunity Zones Got a Second Round, With New Terms

The Opportunity Zone program received an extension and a structural overhaul. OBBBA authorizes a new round of zone designations and modifies the gain-reduction benefit: investors who hold a Qualified Opportunity Fund investment for five years now receive a 10% basis step-up on the deferred gain.

This reform arrives with tighter rules around what qualifies, so investors evaluating a new Opportunity Zone deal should confirm the zone’s current designation status before committing capital. The underlying incentive, deferring and reducing tax on capital gains reinvested into designated zones, remains intact.

6. LIHTC Financing Just Got Easier to Reach

Low-Income Housing Tax Credit deals depend on private activity bond financing to unlock the 4% credit. OBBBA permanently lowered the bond-financing threshold from 50% to 25%, meaning developers now need to finance a smaller share of a project with private activity bonds to qualify for the credit.

OBBBA also added basis boosts of up to 30% for rural and tribal developments. For investors and developers working in affordable housing, this widens the pool of deals that can pencil out under the 4% credit, particularly in markets where bond volume has been the limiting factor.

What This Means for Your Next Acquisition

Every one of these changes rewards investors who plan ahead of closing, not after. Bonus depreciation and Section 179 both hinge on a property’s placed-in-service date and how its components are classified. A cost segregation study is the tool that turns a building’s line items into an asset schedule.

If you’re evaluating a purchase, run the numbers before you close, not at tax time. A qualified cost segregation provider can model the first-year deduction on your specific purchase price and building value, and confirm whether QPP treatment applies to any production-use property in the deal.
